B. A daslrpot 9 secured in any suitable way to the body portion 2 of the device l3 is mnnected with the weighted end 6" of the controlling member 6 by means of a rod it) and forms a governor for the movement of the member 6.

On the side of the thrmving device B adjacent to the point of connection of the shaft C therewith provided a journal 11 which supports a sleeve 12 thereon in such manner as to permit movement of the s: ve longitudinally o the journal. sleeve is formed with an arm 13 connected by a rod 14 with an arm 15 on a shaft 16 carried by the outermost portion of the frame 4, said shaft Till having fixed thereto a curved release member 17 the free end of which is adapted to operate through the opening 6 of the controlling member 6 so to tap or engage the locking catch 8 in such a manner as to trip said catch out of engagement with the detent 7 whereby a. ball held by said detent against release from the throwing device, will be released and projected by the latter. The means to act upon the parts just mentioned so as to effect and time the release action of the detent 7 includes a, releasing disk 18 loosely mounted on the shaft C and shiftable thereon by means of a suitable operating rod 19 leading to a lever or other manually controllable device. The disk 18 is formed with a cam 18 on its periphery which cam is adapted to ooiiperate with a roller 20 supported by another arm 21 which projects from the sleeve 12 in the direction opposite the arm 13.

The cotiperation between the roller 20 and the cam 18" is governed by the position of the sleeve 12 on the journal .1 and it is con templated to shift said sleeve so that during rotation of the device B the members 20 will not coast, other movement of the sleeve being adapted to place said memthnt the release of the at its inner end :2 object to be PIOJCCtGd may then be The movement of the sleeve 12 is gov erned by a setting device adapted to be coir trolled by the controlling member 6 and seen best in Figs. 2 and 4. This setting de vice consists of a lever 22 pivoted to a bracket projecting from a side of the device B, one arm of the lever being attached to an actuating rod 24 the outer end of which rod opi rates through av guide open-- ing 25 in the frame 4 and is adapted to be impinged by the inner or weighted end portion 6" of the controlling member 6. The lever 22 has a yieldable or spring arm 22 the outer end of which, engages in a notch 12 formed in a side of the sleeve 12 and by movement of the lever hereinafter described the sleeve 12 adapted to be shifted iliwerdly and outwardly on the journal 11 whereby the roller 20 may operate on the circular periphery of the disk 1.8 without release of the detent- 7, or may be moved to that portion of the periphery of said disk having the cam 18 so that the latter may actuate the release device comprised by the parts 12, 13 and 2 and thereby ctlect release of the detent 7 so that the ball or objcct may be projected by the device B. There is provided a U-shaped engaging member 26 dctachably and adjustably supported on the outer end of the delivery portion 1 of the throwing device B, opposite the detent 7, which coiiperatcs in the delivery of the ball from the member 1 upon release of the detent.

The details of construction of the invention having been explained, the operation of the machine will be setforth.

Operation: Fig. 2 of the drawings illus trates the parts in the positions assumed thereby justns the ball 27 has been released from the throwing device ll in the project ing operation. As the ball enters the device B the rotation of the latter and centrifugal action causes said ball. to pass to the delivery portion 1 where it, engages with the controlling member 6 which at such time is in the dotted line position shown in Fig. The weight of the ball acting upon the control ling member (3 carries the latter outward to the full line position shown in Fig. 2. overcoming the action of the weighted end 6 of said member 6 in holding said member in said dotted line position. The movement of the ball to the outer extremity of the delivery member 1 is retarded by the daslnpot 9 cooperating with the member 6. When the ball reaches the delivery point of the member B it is detained from being projected by means of the detent 7 but at approximately the same time as the latter coiiperates with the ball the controlling member 6 at its weighted end engages the actuating rod 94 of the setting device, tilts the lever 22 and moves the spring arm 22 outward to shift the sleeve 12 so as to cause the roller 20 to be --iined with the peripiierai portion of i. release device is-now set in operative pooltion torelease the ball 27 from the {latent} the. releaee being actually effected t-y the partial rotation of the sleeve 12 of 7' vmlease device incident to engagement of the .cam 18 and roller 20, the resultant action being an inward pu'ii on t 1e rod 14 causing the release member 17 iii-impinge the a cent arm of the catch Send trip said catch out of engagement with the detent '7, freeing the ball 27 for its projecting movement. The operator controlling the movement of the vrocl l9 and thereby'the disk 18 may remiily shift the disk, so as to vary the time when the min 18 ooects with the roiler l0 and in .this manner. flight of the ball to height is manually governed. As soon as the weightjoi the hall is'removeil from the controlling rnemoer ,6 upon release of the detent 7 it iviil be oh v ions that the. weighted end of the. member G villcarry saiii memi'ser heck to it Giotto-5i line jmsition in and gmerned bythe movement of the hail itself.

The restoration of the detent 7 to iis locked rm 'sitinn in relation to the catch is cites-te l uniiomntiixilly by inean'e of engegemei theinner end of the detent with a. cushioning ah'utment'im, the latter-being locate-(l zit the inner end of 11- slot formed in the delivery portion 1- of the throwing; device B.
